IMPROVEMENT IN TYPES.

Specification forming part of Letters Patent No. 166,205, dated August3, 1875; application filed June 3, 1875.

To all whom it may concern Be it known that I, ANSON M. HOWARD, ofIlion, county of Herkimer and State of New York, have invented a new andImproved Writing and Monogram Type; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings making part of thisspecification, in which Figure 1 is an elevationof my improved typebefore the tin formed in swaging the letter on it is trimmed off. Fig. 2is a similar view of the type after it is finished. Fig. 3 is a top viewof the type shown in Fig. 1.. Fig. 4 is a similar view of the type shownin Fig. 2. Fig. 5 is a vertical section through the forming-die. Fig. 6is an elevation of a typeblank.

The type which I make are designed specially for use in type-Writingmachines; and they are intended to overcome a difficulty heretoforeexperienced from not obtaining from ordinary type a full or completeimpression of the letters of the type upon the paper passed between thetype and the impressionroller. This difficulty results from the type,while they are flat on their lettered ends, being forced up against acylindrical surface, which prevents the flat type coming in contact withthe paper, which is outside of the longitudinal axis of the cylindricalsurface, unless the paper directly under said axis is cut or too deeplyembedded by the type.

My invention consists in making the lettered ends of single metal typein form of a segment of a cylinder, so that when the type are brought upagainst the impression-roller they will exactly fit a segment of thisroller, and thus make a full impression of the letters upon the paper,and the type will be embedded into the paper to an equal extent at allpoints.

The type A shown in the drawing is made of hard metal by swaging theletter upon the type-metal by means of a die-type, B, rolled over thetype-blank.

The process of making this type is the same as is described in myapplication for a process and machine for making hard-metal type, filedin the Patent Office on an even date with this, and need not bedescribed here very particularly.

The die-type B is made with a convex lettered end, and the type A, madefrom the blank 0, has its lettered end swaged'into the form shown at D,Fig. l, by the die A passing a number of times over it, and the fin E,which is formed during this operation, is trimmed oii', so that thefinished type has the form shown in Fig. 2.

Single type made by swagin g the letters upon them are very solid anddurable; and type which have their lettered ends in form of a segment ofa cylinder are very useful, especially when placed on vibrating leversor fingers which print against an impression-roller.

In the drawings the dotted segments of circles are merely drawn for thepurpose of illustratin g the manner in which the improved type will fitthe impression-roller.

What I claim is Single metal type, having their lettered ends made inform of a segment of a cylinder, substantially as and for the purposedescribed.
